Bounced email on Google App Engine

Question

I'm developing application for google app engine (python), witch needs not only to send emails, but also know which ones bounce back.

I created special account for my domain [email protected], added it as an app admin and sending messages from it.

The problem is (and it was described here http://code.google.com/p/googleappengine/issues/detail?id=1800) - GAE sets the Return-Path to some internal email address, not allowing to receive bounced email messages.

Anyone aware of any possible workaround for this? Thanks.

Answer 1

It looks like someone bypassed this problem by switching to Yahoo's Mail API, which uses OAuth and can be used over HTTP. Until google fixes your problem, this looks like a viable solution.

Answer 2

You could use use a third party "email marketing" API like CampaignMonitor that keeps track of the bounced addresses: http://www.campaignmonitor.com/api/method/subscribers-getbounced/

But you'd have to send mail through them, and sync your user list with theirs through their API.

Answer 3

Until the issue is resolved, workaround for my project is using typhoonae, bind mail service to google app's gmail as SMTP (to send messages from [email protected]). When sending this way, [email protected] receives bounced messages.
